Hello everyone,

I just had one question and was wondering if somebody could help me out. Im pretty new at this overclocking stuff and right now I have my HD radeon 7970 at:

GPU clock: 1040
Memory Clock: 1600
VDDC: 1075

I used Trixx for the overclocking. I have been monitoring my fans to control the temp and have been keeping it around 70c.

I have had this overclock running for the past 24 Hours thus far, no hiccups. Just wondering if any of you OC pros know if I am going to blow up my GPU if I keep running it at these settings?

I just built this computer last weekend and bought some really nice toys to go in it. So I hope to keep it for a long time!

if you need any more info, just let me know


Thanks

It's not that it's a club, it's that you can fry your card if you don't know what you're doing! Sorry, I was tired when I posted, so I might have come off a little pretentious.

When you're overclocking, you pick a clock (memory or core) and raise it with small increments and test it while monitoring temps. Then, once you hit instability, you raise the voltage (VDDC) with small increments until you are stable. Then you raise the clocks until unstable. Then raise the voltage. And so forth.

Remember not to let your temps get too high or raise your voltage too much.

That's kind of why I came here , so maybe someone could give me a few pointers. I didn't go completely in the dark with that setting , I just had to search around to see what other people have done. I appreciate your concern, but you make oveclocking sound like its some kind of club. :sarcastic:

Edit: thanks for the quick response though! :)

Thanks for the response. That's exactly what I did when I set it up, which I had learned from another guide. I left the voltage at the default level (hopefully to save on e-bill and not fry my card, which I found out in other forums) and everything seems to be working fine coming into the 48th hour. Temps on this and my 5850 are both under 70C

Edit: when I used catalyst overdrive it read "voltage" and on trixx it's VDDC. Just had to put 2 and 2 together.
